NORFOLK, Va. (AP)  A former Old Dominion University wrestler has filed a lawsuit against the school, saying that despite being knocked out three times over a six-week period and exhibiting symptoms of concussions, coaches failed to refer him for medical treatment.

News outlets report Jordan Marshall says in the lawsuit that he suffered three concussions in May and June 2014. He says head coach Steve Martin and three assistant coaches didn’t refer him for treatment and told him not to complain about his injuries or seek medical attention.

The lawsuit says it wasn’t until Marshall began to “convulse, vomit and spit up blood” that coaches referred him to an athletic trainer.
